• requirements
• AMQP
• gevent + kombu
• solution
• useful links and questions

3. Queues are useful for
• process synchronization
• deferred computations
• slow I/O

4. Somewhere in the code

5. Requirements
• Python 2.x (2.5 or higher)
• gevent
• kombu

6. Advanced Message Queuing
Protocol
• Broker
• Message
• All messages are published into Exchange
• Client consumes messages from Queue
• Messages from Exchange are routed to Queue
based on condition specified by Binding

7. Exchange types
• direct - exact match of message’s Routing Key and
binding’s one
• topic - basic routing based on wildcard matching of
Routing Key treated as zero or more words separated
by «.» («*» - single word, «#» - zero or more words)
• fanout - simple broadcast
• headers - more complicated routing based on custom
headers matching
